Nothing. I think you should buy an ANA grading guide sixth addition and learn how to grade before buying every coin you see on ebay on a whim. Sooner or later, you're going to end up getting a Chinese counterfeit (they actively, legally, counterfeit every dime you can name) or ripped off in some other manner.
You mean NGC???? Sorry, I don't think either of them put out a comprehensive grading book like the ANA does. Do you know what the abbreviations stand for?? Quick!!
Hey everybody You can use Ebays search to see newly listed items first.....this will give you time to ask questions, do your own research, post on forums, etc etc It is a tool Ebay has provided and it is wise to use it.
